But as soon as the media fuss died down she quickly lost interest in the kitten, which remained pink and continued to lick at its pink fur, apparently causing it to ingest some colour from which animal-rights activists say it later died.

The vet that examined the cat when it was taken ill and where it later died already reported that the cat had died from being poisoned by a toxic substance.

Among those that criticised her was artist Yuri Kuklachev who described the stunt as pointless and unnecessarily cruel.

And there is now an online petition demanding the local governor police to investigate the right animal cruelty charges. The petition gathered several thousand signatures but at the moment there has not been an official response from the local government.
